Description

本発明は、室内換気を室内空気と屋外空気をファンモーターによる送風と熱交換素子によって、省エネルギーでおこなうにあたり、屋外からの給気と室内からの排気をダクトを介して行なう熱交換機器において、風路の構成板を形成する技術に関する。   The present invention relates to a heat exchange device that performs indoor air supply and outdoor air through a duct in order to save energy by blowing air from a fan motor and using a heat exchange element for indoor air and outdoor air. The present invention relates to a technique for forming a component plate of a road.

熱交換機器用風路構成板の従来例として図１２〜図１３を参照しながら説明する。   A conventional example of an air path component plate for heat exchange equipment will be described with reference to FIGS.

図１２および図１３に示すように、本体１１４は下面に点検カバー１０１を、側面に室内吸込口１０２と室内吹出口１０３と、屋外吸込口１０４と屋外吹出口１０５を有し、また、中央部内に排気用羽根１０６と給気用羽根１０７を電動機１０８に装着し排気用羽根１０６の外側に排気用ファンケーシング１０９と、給気用羽根１０７の外側に給気用ファンケーシング１１０とを設け、熱交換素子１１１を排気用ファンケーシング１０９および給気用ファンケーシング１１０の外周部に配置し、屋外吸込口１０４から給気用風路構成板１１５と熱交換素子１１１と給気用羽根１０７および吹出管１１７を通じ室内吹出口１０３に連通すると、室内吸込口１０２から排気用風路構成板１１６と熱交換素子１１１と排気用羽根１０６および吹出管１１７を通じ屋外吹出口１０５に連通する排気風路１１３を設けた構成となっている（例えば、特許文献１参照）。   As shown in FIGS. 12 and 13, the main body 114 has an inspection cover 101 on the lower surface, an indoor air inlet 102, an indoor air outlet 103, an outdoor air inlet 104, and an outdoor air outlet 105 on the side surface. The exhaust vane 106 and the air supply vane 107 are attached to the electric motor 108, the exhaust fan casing 109 is provided outside the exhaust vane 106, and the air supply fan casing 110 is provided outside the air supply vane 107. The exchange element 111 is disposed on the outer peripheral portion of the exhaust fan casing 109 and the supply fan casing 110, and the supply air path component plate 115, the heat exchange element 111, the supply blade 107, and the outlet pipe from the outdoor suction port 104. When communicating with the indoor outlet 103 through 117, the exhaust air passage constituting plate 116, the heat exchange element 111, the exhaust vane 106, and the outlet pipe are communicated from the indoor inlet 102. It has a structure in which a discharge air path 113 which communicates with the outdoor air outlet 105 through 17 (for example, see Patent Document 1).

この構成において、屋外吸込口１０４から吸引される屋外吸込空気１１８が冷たく、室内吸込口１０２から吸引される室内吸込空気１１９が暖かい状態となる冬季等の場合、給気風路１１２と排気風路１１３に介在する熱交換素子１１１によって、排気風路１１３の空気は、給気風路１１２の空気に熱量を奪われることによって減熱され、室内吸込空気１１９よりも低い温度で、排気用羽根１０６によって吹出管１１７通り、屋外吹出口１０５を介し、屋外吹出空気１２０として屋外に排気される。一方、給気風路１１２の空気は、排気風路１１３の空気から熱量を加えられることによって加熱され、屋外吸込空気１１８よりも高い温度で、給気用羽根１０７によって吹出管１１７通り、室内吹出口１０３を介し、室内吹出空気１２１として室内に給気される。しかしながら、排気風路１１３に介在している電動機１０８からの発熱エネルギーは、室内吹出空気１２１の加熱には利用されず、屋外吹出空気１２０として屋外へ排気されている。   In this configuration, in the winter season when the outdoor intake air 118 sucked from the outdoor intake port 104 is cold and the indoor intake air 119 sucked from the indoor intake port 102 is in a warm state, the supply air passage 112 and the exhaust air passage 113 are used. The air in the exhaust air passage 113 is reduced in heat by the heat in the air supply air passage 112 being taken away by the heat exchange element 111 interposed in the air, and blown out by the exhaust vane 106 at a temperature lower than the indoor intake air 119. The air is exhausted outdoors as outdoor air 120 through the pipe 117 and the outdoor air outlet 105. On the other hand, the air in the supply air passage 112 is heated by adding heat from the air in the exhaust air passage 113, and is heated at a temperature higher than the outdoor intake air 118 by the supply blades 107 through the outlet pipe 117 and the indoor outlet. The air is supplied into the room as indoor blowing air 121 through 103. However, the heat generation energy from the electric motor 108 interposed in the exhaust air passage 113 is not used for heating the indoor blowing air 121 but is exhausted to the outside as the outdoor blowing air 120.

また、屋外吸込口１０４から吸引される屋外吸込空気１１８が暖かく、室内吸込口１０２から吸引される室内吸込空気１１９が冷たい状態となる夏季等の場合、給気風路１１２と排気風路１１３に介在する熱交換素子１１１によって、排気風路１１３の空気は、給気風路１１２の空気から熱量を加えられることによって加熱され、室内吸込空気１１９よりも高い温度で、排気用羽根１０６によって吹出管１１７通り、屋外吹出口１０５を介し、屋外吹出空気１２０として屋外に排気される。一方、給気風路１１２の空気は、排気風路１１３の空気に熱量を奪われることによって減熱され、屋外吸込空気１１８よりも低い温度で、給気用羽根１０７によって吹出管１１７通り、室内吹出口１０３を介し、室内吹出空気１２１として室内に給気される。しかしながら、給気風路１１３に介在している電動機１０８からの発熱エネルギーは、屋外吹出空気１２０として屋外に排気されず、減熱すべく室内吹出空気１２１を加熱して室内へ給気されている。
特開２００６−３４９２２３号公報 Further, in the summer season when the outdoor intake air 118 sucked from the outdoor intake port 104 is warm and the indoor intake air 119 sucked from the indoor intake port 102 is in a cold state, the air supply air passage 112 and the exhaust air passage 113 are interposed. The air in the exhaust air passage 113 is heated by adding heat from the air in the air supply air passage 112 by the heat exchanging element 111 that is heated to a temperature higher than the indoor intake air 119 by the exhaust vane 106 and the outlet pipe 117. Then, the air is exhausted outdoors as outdoor air 120 through the outdoor air outlet 105. On the other hand, the air in the supply air passage 112 is reduced in heat by the air in the exhaust air passage 113 being deprived of heat, and at a temperature lower than that of the outdoor intake air 118, the air supply blades 107 pass through the outlet pipe 117 and the indoor The air is supplied into the room as indoor blowing air 121 through the outlet 103. However, the heat generation energy from the electric motor 108 intervening in the supply air passage 113 is not exhausted to the outside as the outdoor blowing air 120, but the indoor blowing air 121 is heated and supplied to the room to reduce the heat.

屋外吸込口５から吸引される屋外吸込空気２３が冷たく、室内吸込口３から吸引される室内吸込空気２４が暖かい状態となる冬季の暖房時を主として使用する場合の説明をする。室内を暖房する場合、給気風路１５と排気風路１８に介在する熱交換素子１２によって、排気風路１８の空気は、給気風路１５の空気に熱量を奪われることにより減熱され、排気用羽根７によって室内吸込空気２４よりも低い温度で、屋外吹出口６を介し、屋外吹出空気２５として屋外に排気される。一方、給気風路１５の空気は、排気風路１８の空気から熱量を加えられることによって加熱され、給気用羽根８によって、屋外吸込空気２３よりも高い温度で、室内吹出口４を介し、室内吹出空気２６として室内に給気される。このとき、排気用羽根７と給気用羽根８に装着された電動機９は、印加される入力に対し２０〜９０％の効率で送風エネルギーとして出力されるが、残りの１０〜８０％は電動機９の発熱エネルギーとして発熱される。電動機９が取り付く風路仕切板１９は、排気用ファンケーシング１０側に窪ませ、凹凸部１９ａとした構成となっているため、排気用羽根７と給気用羽根８を駆動させるために発生する発熱エネルギーを、排気風路１８に伝えず給気風路１５内に放熱することになり、熱交換素子１２によって加熱された給気風路１５の空気は、さらに加熱され室内吹出空気２６として室内に給気される。熱交換素子１２の熱交換効率は、式１で表すことができるので、室内吸込空気２４と屋外吸込空気２３の温度が同じであるため分母が同じとなり、分子の室内吹出空気２６の温度が高くなり大きくなるため、熱交換効率を向上することができることとなる。   A description will be given of a case where the outdoor intake air 23 sucked from the outdoor suction port 5 is mainly used during the heating in winter when the indoor suction air 24 sucked from the indoor suction port 3 is in a warm state. When the room is heated, the heat exchange element 12 interposed between the supply air passage 15 and the exhaust air passage 18 reduces the heat of the air in the exhaust air passage 18 by the heat of the air in the supply air passage 15 being deprived of heat. The blades 7 are exhausted to the outside as outdoor blowing air 25 through the outdoor blowing outlet 6 at a temperature lower than the indoor suction air 24. On the other hand, the air in the supply air passage 15 is heated by adding heat from the air in the exhaust air passage 18 and is heated by the air supply blade 8 at a temperature higher than the outdoor intake air 23 through the indoor outlet 4. The air is supplied into the room as indoor blown air 26. At this time, the motor 9 mounted on the exhaust blade 7 and the air supply blade 8 is output as blowing energy with an efficiency of 20 to 90% with respect to the applied input, but the remaining 10 to 80% is the motor. Heat is generated as heat generation energy of 9. The air passage partition plate 19 to which the electric motor 9 is attached is recessed to the exhaust fan casing 10 side and has a concavo-convex portion 19a, and is generated to drive the exhaust vane 7 and the air supply vane 8. The generated heat energy is dissipated into the supply air passage 15 without being transmitted to the exhaust air passage 18, and the air in the supply air passage 15 heated by the heat exchange element 12 is further heated and supplied to the room as indoor blowing air 26. I care. Since the heat exchange efficiency of the heat exchange element 12 can be expressed by Equation 1, since the temperature of the indoor intake air 24 and the outdoor intake air 23 is the same, the denominator is the same, and the temperature of the numerator indoor blowing air 26 is high. Therefore, the heat exchange efficiency can be improved.

また、風路仕切板１９を排気用ファンケーシング１０側に窪ませ、凹凸部１９ａとした構成となっているため、排気側電動機９ａと給気側電動機９ｂを一体で構成した電動機９は、給気風路１５と排気風路１８に均等に張り出し、給気用羽根８の吸込み空間と排気用羽根７の吸込み空間が同等に確保され、吸込み圧損が同等となる。   Further, since the air passage partition plate 19 is recessed to the exhaust fan casing 10 side to form an uneven portion 19a, the motor 9 in which the exhaust side electric motor 9a and the supply side electric motor 9b are integrally formed is provided with The air flow path 15 and the exhaust air path 18 are evenly projected, and the suction space of the air supply blade 8 and the suction space of the exhaust blade 7 are ensured equally, and the suction pressure loss becomes equal.

このように本発明の実施の形態１の熱交換機器によれば、電動機取付のための構造が簡素化にしつつ電動機周囲の通風性が向上するので、電動機をコンパクトに収納しながら電動機の発熱を積極的に有効活用することで熱交換効率を向上することができ、特に暖房時の熱交換効率を向上することができることとなる。   As described above, according to the heat exchanging device of Embodiment 1 of the present invention, the air permeability around the motor is improved while simplifying the structure for mounting the motor, so that the motor generates heat while storing the motor in a compact manner. By actively utilizing it effectively, the heat exchange efficiency can be improved, and in particular, the heat exchange efficiency during heating can be improved.

なお、図６に示すように給気側電動機９ｂと排気側電動機９ａを分けて構成し、給気側電動機９ｂと排気側電動機９ａを給気風路１５内に介在させる構造も可能であるが、給気風路１５内に介在する排気側電動機９ａが熱交換素子１２の上流側となるため、排気側電動機９ａで発生するすべての発熱エネルギーを利用することは出来ないが、熱交換素子１２へ流入する屋外吸込空気２３の温度を上昇することができるので、排気側電動機９ａの発熱エネルギーをそのまま屋外吹出口６から屋外へ排気するよりも熱交換効率を向上することができる。   In addition, as shown in FIG. 6, a structure is possible in which the supply-side motor 9b and the exhaust-side motor 9a are configured separately, and the supply-side motor 9b and the exhaust-side motor 9a are interposed in the supply air passage 15. Since the exhaust side electric motor 9a interposed in the supply air passage 15 is on the upstream side of the heat exchange element 12, it is not possible to use all the heat generation energy generated in the exhaust side electric motor 9a, but it flows into the heat exchange element 12 Since the temperature of the outdoor intake air 23 to be increased can be increased, the heat exchange efficiency can be improved as compared with the case where the heat generation energy of the exhaust-side electric motor 9a is directly exhausted from the outdoor outlet 6 to the outside.

図９および図１０に示すように、熱交換機器としての本体１は、側面に室内吸込口３と室内吹出口４と、屋外吸込口５と屋外吹出口６を有し、排気用羽根７と給気用羽根８を電動機９に装着し排気用羽根７の外側に排気用ファンケーシング１０と、給気用羽根８の外側に給気用ファンケーシング１１とを設け、熱交換素子１２の風下側に排気用羽根７を配置し、屋外吸込口５から給気用羽根８および給気用吹出管１４と熱交換素子１２とを通じ室内吹出口４に連通する給気風路１５と、室内吸込口３から熱交換素子１２と排気用羽根７および排気用吹出管１７とを通じ屋外吹出口６に連通する排気風路１８と、給気風路１５と排気風路１８を隔てる仕切り部材としての風路仕切板１９に電動機９を排気風路１８側に設けた構成となっている。   As shown in FIGS. 9 and 10, the main body 1 as a heat exchange device has an indoor inlet 3, an indoor outlet 4, an outdoor inlet 5, and an outdoor outlet 6 on the side surface, An air supply vane 8 is mounted on the electric motor 9, an exhaust fan casing 10 is provided outside the exhaust vane 7, and an air supply fan casing 11 is provided outside the air supply vane 8. The exhaust air vane 7 is disposed in the air supply air passage 15, which communicates with the indoor air outlet 4 from the outdoor air inlet 5 through the air supply blade 8, the air supply outlet pipe 14 and the heat exchange element 12, and the indoor air inlet 3. To the outdoor air outlet 6 through the heat exchange element 12, the exhaust vane 7 and the exhaust outlet pipe 17, and the air path partition plate as a partition member separating the supply air path 15 and the exhaust air path 18. 19, the electric motor 9 is provided on the exhaust air passage 18 side.

次に、図７〜図１０を用いて動作を示す。   Next, the operation will be described with reference to FIGS.

屋外吸込口５から吸引される屋外吸込空気２３が暖かく、室内吸込口３から吸引される室内吸込空気２４が冷たい状態となる夏季の冷房時を主として使用する場合、給気風路１５と排気風路１８に介在する熱交換素子１２によって、排気風路１８の空気は、給気風路１５の空気から熱量を加えられることにより加熱され、排気用羽根７によって室内吸込空気２４よりも高い温度で、屋外吹出口６を介し、屋外吹出空気２５として屋外に排気される。一方、給気風路１５の空気は、排気風路１８の空気から熱量を奪われることによって減熱され、給気用羽根８によって、屋外吸込空気２３よりも低い温度で、室内吹出口４を介し、室内吹出空気２６として室内に給気される。   When mainly used during cooling in summer when the outdoor intake air 23 sucked from the outdoor intake port 5 is warm and the indoor intake air 24 sucked from the indoor intake port 3 is cold, the supply air passage 15 and the exhaust air passage The heat exchange element 12 interposed in the air 18 heats the air in the exhaust air passage 18 by adding heat from the air in the air supply air passage 15, and the outdoor air at a temperature higher than the indoor intake air 24 by the exhaust vanes 7. The air is exhausted to the outside as the outdoor air 25 through the air outlet 6. On the other hand, the air in the supply air passage 15 is reduced in heat by taking the amount of heat from the air in the exhaust air passage 18, and is supplied to the air supply blade 8 through the indoor outlet 4 at a temperature lower than the outdoor intake air 23. Then, the air is supplied into the room as the indoor blowing air 26.

このとき、排気用羽根７と給気用羽根８に装着された電動機９は、印加される入力に対し２０〜９０％の効率で送風エネルギーとして出力されるが、残りの１０〜８０％は電動機９の発熱エネルギーとして発熱される。電動機９が取り付く風路仕切板１９を給気用ファンケーシング１１側に窪ませ、凹凸部１９ａとした構成となっているため、排気用羽根７と給気用羽根８を駆動させるために発生する発熱エネルギーを、給気風路１５に伝えず排気風路１８内に放熱し、屋外吹出空気２５として屋外へ排気することにより、熱交換素子１２によって減熱された給気風路１５の空気は、電動機９の発熱エネルギーによって加熱されることなく室内吹出空気２６として室内に給気される。熱交換素子１２の熱交換効率は、式２で表すことができるので、室内吸込空気２４と屋外吸込空気２３の温度が同じであるため分母が同じとなり、分子の室内吹出空気２６の温度が電動機９の発熱エネルギーによって高くならないため、熱交換効率を向上することができることとなる。   At this time, the motor 9 mounted on the exhaust blade 7 and the air supply blade 8 is output as blowing energy with an efficiency of 20 to 90% with respect to the applied input, but the remaining 10 to 80% is the motor. Heat is generated as heat generation energy of 9. Since the air passage partition plate 19 to which the electric motor 9 is attached is recessed toward the air supply fan casing 11 to form the uneven portion 19a, it is generated to drive the exhaust blade 7 and the air supply blade 8. The heat generated in the supply air passage 15, which has been reduced in heat by the heat exchange element 12, is radiated into the exhaust air passage 18 without being transmitted to the supply air passage 15 and exhausted to the outside as the outdoor blowing air 25. The indoor air is supplied to the room without being heated by the heat generation energy 9. Since the heat exchange efficiency of the heat exchange element 12 can be expressed by Equation 2, since the indoor intake air 24 and the outdoor intake air 23 have the same temperature, the denominator is the same, and the temperature of the numerator indoor air 26 is the electric motor. Therefore, the heat exchange efficiency can be improved.

また、風路仕切板１９を給気用ファンケーシング１１側に窪ませ、凹凸部１９ａとした構成となっているため、排気側電動機９ａと給気側電動機９ｂを一体で構成した電動機９は、給気風路１５と排気風路１８に均等に張り出し、給気用羽根８の吸込み空間と排気用羽根７の吸込み空間が同等に確保され、吸込み圧損が同等となる。   In addition, since the air passage partition plate 19 is recessed to the air supply fan casing 11 side to form a concavo-convex portion 19a, the electric motor 9 configured integrally with the exhaust side electric motor 9a and the air supply side electric motor 9b is: The air supply passage 15 and the exhaust air passage 18 are evenly projected, so that the suction space of the supply blade 8 and the suction space of the exhaust blade 7 are ensured equally, and the suction pressure loss becomes equal.

このように本発明の実施の形態２の熱交換機器によれば、電動機９取付のための構造が簡素化にしつつ電動機９周囲の通風性が向上するので、電動機９をコンパクトに収納しながら電動機の発熱を効率よく排気することで熱交換効率を向上することができ、特に冷房時の熱交換効率を向上することができることとなる。   As described above, according to the heat exchange device of the second embodiment of the present invention, the air permeability around the motor 9 is improved while the structure for mounting the motor 9 is simplified. The heat exchange efficiency can be improved by exhausting the heat generated efficiently, and in particular, the heat exchange efficiency during cooling can be improved.

なお、図１１に示すように給気側電動機９ｂと排気側電動機９ａを分けて構成し、給気側電動機９ｂと排気側電動機９ａを排気風路１８内に介在させる構造も可能であるが、排気風路１８内に介在する給気側電動機９ｂが熱交換素子１２の上流側となるため、給気側電動機９ｂで発生するすべての発熱エネルギーを排気することは出来ないが、熱交換素子１２を介することで給気側電動機９ｂで発生する発熱エネルギーを抑制し、室内吹出空気２６の温度上昇を抑えることができるので、給気側電動機９ｂの発熱エネルギーをそのまま室内吹出口４から室内へ給気するよりも熱交換効率を向上することができる。   As shown in FIG. 11, it is possible to configure the supply side motor 9b and the exhaust side motor 9a separately so that the supply side motor 9b and the exhaust side motor 9a are interposed in the exhaust air passage 18. Since the supply side electric motor 9b interposed in the exhaust air passage 18 is upstream of the heat exchange element 12, it is impossible to exhaust all the heat generation energy generated in the supply side electric motor 9b, but the heat exchange element 12 Since the heat generation energy generated in the air supply side motor 9b can be suppressed and the temperature rise of the indoor blown air 26 can be suppressed, the heat generation energy of the air supply side motor 9b is supplied to the room from the indoor outlet 4 as it is. The heat exchange efficiency can be improved rather than being concerned.

本発明の熱交換機器は、本体高さを低く保ちながら、熱交換効率を向上させることが可能なため、天井裏寸法の確保が難しい近年の居住および非居住の建築物の換気装置として有用である。   The heat exchange device of the present invention can improve the heat exchange efficiency while keeping the body height low, and is useful as a ventilator for recent residential and non-residential buildings where it is difficult to secure the dimensions of the ceiling. is there.
